Momentary loss off power/or stutter

Hi everyone,

I have a 01 expedition.

When I accelerate softly, coasting, or going up a hill my car beings to stutter.
I should define stutter. It feels like the car is lossing power for less than a second. The happens in relatively quick succesion. If I add more gas it will stutter once and then seems to be fine.

I would like to fix this myself (cheaper obviously).

Any suggestions?

Thanks in advance for everyones help.

Agreed. When I changed mine last, I made myself red in the face trying to blow air through it. Interesting how much more responsive engines are when they can get some fuel, isn't it?

check engine light off?

I have the same thing happening. My check engine light does not come on so I'm stumped. So far I have replaced the plugs and the coil boots. Mine has 75000 miles so I don't mind throwing a few parts at it to try and fix. I have never had a fuel filter be the root source of a missing problem- although I would replace it because it's the right thing to do if it is getting old. I think the fuel filter failing would cause problems when you really gas it. Most of my problems have been under very light acceleration. I had a similar experience on my old aerostar. What ended up fixing a miss/stumble that did not turn on the check engine light was replacing the oxegen sensor. I'm thinking about doing that on my expedition although I think newer vehicles might have multiple sensors so this might be an expensive bunny trail.
